1. A compensated microelectromechanical oscillator, comprising:

  • a microelectromechanical oscillator to generate an output signal wherein the output signal includes a first frequency, the microelectromechanical oscillator comprises;

    a microelectromechanical resonator; and

    drive circuitry, coupled to microelectromechanical resonator, to output a drive signal to the microelectromechanical resonator;

    control circuitry, coupled to the drive circuitry, to output a control signal which adjusts the drive signal from the drive circuitry; and

    frequency adjustment circuitry, coupled to the microelectromechanical oscillator to generate an output signal having a second frequency using the output signal of the microelectromechanical oscillator and a set of values, wherein the second frequency is greater than the first frequency.
